What is claimed is: ,A

1. In a railway truss type brake beam including a compression member and a tension rod with their end portions converging, a brake head member receiving said end portionsand a device on the end of the tensio-n rod thrusting the brake head member against the endrof the compression member, and an element integral with one of said members and interlocking with Va `part of the other jmember and preventing disassembly .of said members. Y

. 2. In a railway truss type brake beam including a compression member and a tension rod with their lend portions converging, a brake head member receiving said endV portions, one of said members having a bendable lug and the other of-said members having an opening into which said lug extends, when bent over, and prevents disassembly of said members. Y

3. In a railway truss type ing a compression member and a Vtension memberwith their end portions converging, a brake l.head receiving said `end portions, and a device on the end ofthe tension Ymember thrusting the ,brake headv against the end of the compression memben a bendable element on the head, the

compression member being provided with an aperture receiving a portion ,of said, element to hold the head against removal Vfrom the compression member.

4. In a railway truss type brake beam includy ing a compression -member h-aving an aperture Y 4spaced inwardly from the end of the beam, a

tension'member, the end portions ofsaid compressionV and tension members converging, a brake headrhaving'sides facing towards and away from the end of the beam respectively, thehead -also having elements for mounting Va brake shoe facing transversely of the beam, there being :a recess opening inwardly of the head from the side vfacing away from the end of the beam, said 4 hold the head and compression member against disassembly.

6. In a railway truss type brake beam including a compression member and a tension member with their end portions converging, a brake head receiving said end portions, and a device on the end of the tension member thrusting the brake head against the.V end of the compression member, there being an aperture between the head sides, and the compression member having an element accessible through the open end of said recess in the head and bendable by a tool inserted through said recess so as to enter said aperture.

In a railway truss type brake beam including` a compression member and a tension member with their end portions converging, a brake Vhead receiving said end portions, and a device on the end of the tension member thrusting the brake head against the end of the compression member, there being a tension member'receiving sleeve at the side of the head spaced-from said device, a'bendable lug on the head spaced from said device a greater distance than said sleeve, the compression member being provided with an aperture similarly spaced from said device and receiving a'portion of said element to holdthe headV against removal from the compression member. Y, Y y Y 8. In a railway Vtruss type brakebeam includving a compression member and a tension member with their end portions converging, Aa brake head receiving said end portions, and a device on the end of the tension member thrusting the brake head againstY the end of the compression member, there being a tension member-receiving sleeve at the side of the head spaced from said Y device, a bendable lug on the'head intermediate recess being at the rear of said elements and 'receiving the end portion of theVV compression kmembeiz the rear of the head forming a wall of said recess and having a lug extending away Y `Vfrom the end ofthe beam beyond the head sideY facing away Vfrom the end of the beam and bent into said aperture to retain 'the headV against 'removal from the compression member.

' Ina railway truss type *brake beam includingf' aA compression'member and a tension mem- "ber withtheir end portions converging, a brake 'head rceivingsaid portions, and a'device on the'end of the tension memberV thrusting the brake head'against the end of the compression f'member, a bendableV element on the compresslon vmember, the head beingl provided with an *aperture receiving atportion of said'element to the sidesV thereof, the Ycompression member being provided with an aperture intermediate the sides of the head and receiving a portion of said element to hold the head .against removal from the compression member.r Y

9. A railway brake head having a recess arranged to receive the end portion of Ya beam compression member, and having an aperture for a beam tension member, one side of the head formingV a seat for lthe end of such memberV and a bearing fora tensioning device, there being a lug on the head spaced from said seat and bendable into a position to face in the direction opposite to that faced by said seat.

V10. A railway brake head having a part arranged to mount a brake shoe and to receive and seat th'e end of -a beam compression member and having a bearing at'V one side'for a'tensionving device, and arlug projecting from the other side of the'body and bendable to oppose said latter mentionedside. v 1'1. A- railway brake head vcomprising a body,

the front of which is arranged to mount a brake shoe Vand having aV recess 'extending inwardly from one side for receiving the end'por'tion of a beam compression memben'the inner end of the recess forming a seat for the end of the member, there being a bearing on' the outer'face beam tension member, one side of the head form- DONALD E.
